Here's fixed/updated install files to MDK 9.1:

What do they fix?

the boot problem with Promise based IDE controllers, by setting "CONFIG_PDC202XX_FORCE=Y"

the VESA framebuffer problem that hangs systems with 1024 MB of RAM or more...
(the same patch that got accepted and is used in 2.4.21-rc7-ac1...,
and no more need for vram boot option, even if it is kept for override capability)

nForce2 UDMA/133 reporting (but it wont program the hardware above UDMA/100 for now)

Since theese updates/fixes are somewhat large I decided to try and make it easier to install and update the MDK 9.1.
So I made a CD image with updated boot-kernel that will use the original 9.1 CD:s for the actual install.

Here it is: mdk_91_fix.iso (about 16MB)
It has the following features:

updated boot-kernel (for install, supports every command that the original disks did)

NEW: 'hd' boot option (install from hd)

NEW: 'net' boot option (install from network)

NEW: 'memtest' boot option (runs memtest86 v.3.0 from CD)

Here is how to use it:

1. burn image to cd (obviously...)
2. boot with the cd as you would have with the original MDK 9.1
3. when the installer complains: "That CDROM disk does not seem to be a Mandrake Linux Installation cdrom!":

Here's how to use them:

Download them to your computer and write the images to floppy disks.(you'll need at least 2 of the files above, one "boot", and one
depending on the kernel you wan't to update...)
the command under Linux is: "dd if=name_of_image of=/dev/fd0 bs=512"
